Revealing mistake: Throughout the movie closeups of Enik's eyes reflect the lights and set around him that aren't part of the movie. During the scene when he's talking to Dr. Marshall about how the crystal controls the sleestack, you can see the white ceiling of the soundstage and lights which instead should be the sky.

1 revealing mistake
Directed by: Brad Silberling
Starring: Will Ferrell, Anna Friel, Danny McBride, Jorma Taccone
Continuity mistake: When Grumpy jumps the chasm to chase Dr. Marshall, there's a large green bulbous plant that moves from the side Grumpy jumped from to the one he lands on. It wasn't there before.
Dr. Rick Marshall: If you don't make it, it's your own damn "vault." That's a bitch slap of truth right there.
Question: Has it been explained how all those animals (and primates) ended their lives in the tyrannosaurus rex's lair? Did all of them get there by the sand trap(s)? If so, who re-hid them after they had been walked into? Perhaps the lair was used as sacrificial grounds or execution by the primates?
